Special Issue Information

Dear Colleagues,

Cancer is a major cause of morbidity and mortality worldwide, posing a tremendous burden on both individuals and on society as a whole. Although primary prevention is of high priority, it has become increasingly important to focus on cancer survivors. Currently, more people are living with and surviving from cancer than ever before, partly due to the positive developments in this field, such as earlier detection and/or better treatment for several cancer types.

Nutrition plays an important role in cancer prevention, and, currently, evidence-based dietary recommendations exist, which, if implemented, have the ability to lower cancer risk. Nevertheless, evidence on the role of nutrition following cancer is limited. Cancer survivors are advised to follow, unless otherwise told, the dietary recommendations that apply for cancer prevention after the acute stage of treatment.   

Considering the success of the previous Special Issue "Nutrition for Cancer Survivors", we are pleased to announce that we are launching a second Special Issue on this topic. The objective of this Special Issue on “Nutrition for Cancer Survivors II” is to continue to elucidate the relevance of nutrition and other nutrition-related factors (e.g., body weight), with a focus on the post-diagnosis period and following cancer treatment, with cancer-specific and all-cause mortality, cancer recurrence and survival, as well as with other health-related outcomes, among cancer survivors. The optimal goal is to contribute to the development of evidence-based dietary recommendations tailored specifically to cancer survivors, and to promote the health and well-being of this growing population.

In Switzerland, there is a large seasonal variation in sunlight, and vitamin D deficiency is relatively common during winter. The season of diagnosis may be linked to cancer survival via vitamin D status. Using data from the Cancer Registry of Zurich, Zug, Schaffhausen, and Schwyz with more than 171,000 cancer cases registered since 1980, we examined the association of the season of diagnosis with survival for cancers including prostate (ICD10 code C61; International Categorization of Diseases, version 10), breast (C50), colorectal (C18-21), lung (C34), melanoma (C43), and all sites combined. Cox proportional hazards regression models were used to assess the differences in the all-cause mortality by the season of the diagnosis. Winter was used as the reference season. Hazard ratios (HR) and 95% confidence intervals (CI) were calculated for all the cancers combined (excluding nonmelanoma skin cancer) and for prostate (in men), breast (in women), colorectal, lung cancer, and melanomas, separately. A diagnosis in summer and/or autumn was associated with improved survival in all the sites combined for both sexes (men: HR 0.97 [95% CI 0.96–0.99]; women: HR 0.97 [95% CI 0.94–0.99]) and in colorectal (HR 0.91 [95% CI 0.84–0.99]), melanoma (HR 0.81 [95% CI 0.65–1.00]), and breast cancer (HR 0.91 [95% CI 0.94–0.99]) in women. Our study results suggest that a cancer diagnosis in summer and/or autumn is associated with a better prognosis. The improved seasonal survival coincides with the seasonal variation of sun-induced vitamin D, and vitamin D may play a protective and beneficial role in cancer survival. Full article

The role of overall diet on longevity among cancer survivors (CS) needs further elucidation. We performed a systematic review of the literature and a meta-analysis of related cohort studies published up to October 2022 investigating post-diagnosis a priori (diet quality indices) and a posteriori (data-driven) dietary patterns (DPs) in relation to all-cause and cancer-specific mortality. Pooled hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using random-effects meta-analyses comparing highest versus lowest categories of adherence to DPs. We assessed heterogeneity and risk of bias in the selected studies. A total of 19 cohort studies with 38,846 adult CS, some assessing various DPs, were included in the meta-analyses. Higher adherence to a priori DPs was associated with lower all-cause mortality by 22% (HR = 0.78, 95% CI: 0.73–0.83, I2 = 22.6%) among all CS, by 22% (HR = 0.78, 95% CI: 0.73–0.84, I2 = 0%) among breast CS and by 27% (HR = 0.73, 95% CI: 0.62–0.86, I2 = 41.4%) among colorectal CS. Higher adherence to a “prudent/healthy” DP was associated with lower all-cause mortality (HR = 0.79, 95% CI: 0.64–0.97 I2 = 49.3%), whereas higher adherence to a “western/unhealthy” DP was associated with increased all-cause mortality (HR = 1.48, 95% CI: 1.26–1.74, I2 = 0%) among all CS. Results for cancer-specific mortality were less clear. In conclusion, higher adherence to a “healthy” DP, either a priori or a posteriori, was inversely associated with all-cause mortality among CS. A “healthy” overall diet after cancer diagnosis could protect and promote longevity and well-being. Full article
